Difference in installing a 32 or 40 amp level 2 charger?

[delacruz.c5d]

The mobile charger should work fine. See page 2 of the attachment.

However, note that it is controlled by the car and the FordPass app. Yes, you can easily set the hours. Whether the car chooses to follow them 100% of the time...

Agreed...you can possibly control when the vehicle charges in two ways:
1) Setup a charging schedule with the MME, or
2) Setup a charging schedule with the EVSE, if it can do it.

Personally, I just have the EVSE set to supply power all the time, and I schedule the allowed charge window via the MME. I've decided to do it this way, as most of my departure times for preconditioning the vehicle are outside of the charge window, and I didn't want to have to play schedule 3D chess when I can't even handle checkers sometimes.

Obs, people can do it however they feel comfortable and what makes the best sense for them. I live in the cold bitter Midwest, so this is the solution that I have stumbled upon, and it works for me.

As always, you e-mileage will vary. Best of luck!

Ok thanks for all the info guys. I figured out that I do have room in my sub panel to put in a 14-50 outlet. With the Ford plug. Do I need a 50 amp breaker or can I use a 30 or a 40?

You need a 50 Amp breaker, as a 14-50 calls for a 50 Amp circuit. The EVSE will only draw 40 amps, as the circuit needs to be sized 125% over by some code of some sort...I think it's a national code...

Got it. Thanks.
I was just talking to my friend about me getting the MME and he was saying he don’t trust EVs at all right now. Heard stories of a guy needing a battery and it costing $20,000 or something on a Tesla

Honestly, this will depend on the electrical codes where you live. The ford Mobil charger will draw 32 amps. This is safe on a 40 amp circuit / breaker. I had this set up for months. But if code in your area requires a 50 amp circuit for a 14/50 outlet… then that’s what you’ll need.

40 it is then. Lol

But if 110 charges 2 miles per hour then 24 miles per day will get me behind I guess. Is there smaller to an 32A?

I was thinking:
110 & 12 amps will charge 1.32 KW/h
Give up some to heat loss, and call it 1.2 KW/h
You said you had 13 hours to charge / night. So you can recover. 15.6kwh recovered each night.
Over 7 nights that’s 109 kwh recovered per week.
That’s about 120% of my extended range battery, which SHOULD get 270 miles at 100%. So that SHOULD be 320ish miles of driving / week just from a 110 socket. Even at colder temps, should be 240ish.
You said you need 240 miles for commute. So 110 socket should be doable.
Yes your SOC will decrease slowly through the week but will pick back up when you’re not commuting on the weekend.

True. I have such an easy run of putting in a 240 socket also. Thank you

you should know better as a firefighter.

If the outlet is rated for 50amps, there is a good chance somebody will plug in a 50amp load someday. However, you ALSO need to be sure the wires between outlet and circuit breaker are sized to carry what the breaker will allow. Wire size and breaker max are usually upsized from actual loads if the loads are expected to run for more than 3 hours..... so nothing gets hot and starts a fire.

with the ford mobile charger pulling 32amps, you will be SAFEST with NEMA 14-50 outlet, and all three load wires (L1, L2, N) being 6awg copper even though N is not 'used' by chargers, and the ground wire being 8awg.

Don't cheap out and skip the N wire or go with small wire... wiring needs to support what the breaker will allow to avoid heating up.

The real difference, I believe, will be effective charging speed and effective load. Higher amp means more charge per time while also being a larger electrical load. There are several good YouTube reviews of the various chargers so watch and that should help you decide. Several of the reviews mention that the portable charger may be all you need. Personally I purchased a ChargePoint which is currently adorning my wall while I await delivery.

Me too, should take delivery this week ?

6 gauge with 14-50 outlet and 40 amp should suffice. This is only for MME. I guess the breaker 40 or 50 doesn’t matter. I can use either

I have a ChargePoint unit hardwired to a 50 amp circuit breaker. I charge at 9.67 KWH in that configuration.

Maybe he wants his friends from the station to come over for a barbecue of his house?

You can get by with a 40A breaker for a 32A charger, but if you have the capacity in the breaker box, I'd use a 50A breaker instead. Gives you more flexibility, both in choice of chargers, and in case your drive pattern ever changes at some point and you want the ability to charge faster. Or if your power company later enacts cheap time-of-day rates for a smaller time window overnight.

It sounds like maybe you're parking outside? The included Ford Mobile Charger will work outside, but mobile chargers are lightweight units. If you're going to be plugging in regularly, sometimes in bad weather, a more heavy duty unit isn't the worst idea. Many of us got a Grizzl-E ($459). It has a heavy cable and is solidly built (made in Canada, UL Listed). It's a 40A unit, but can be dialed down to 32A, 24A, or 16A if desired. (I dropped mine to 24A since I don't need more, and lower is always a bit safer.)
